Wat Lak Kaen is some where that I visited when I was traveling from Phang Nga to Phuket.
We nearly missed it but it is just beside the road.
"Wat Lak Kaen is a temple in the Takua Pa district, and it is south of Khao Lak. At least parts of it were destroyed by the 2004 tsunami, including the ubosot, which is the holiest building in a temple complex and is the place where new priests or monks are ordained" - text courtesy of Aleenta.
Wat Lak Kaen was empty when I visited which meant that it was a little spooky...
I did enjoy looking at the murals that were painted on the buildings.
